Hi Ray, complicated set-up I'm afraid; I'm not sure how many children she actually had.
The 1911 says Sarah is single (widow crossed out), and that she had 6 children from the 'marriage', 2 have died (this is crossed out). William (22) is the only child still with her by 1911.
Sarah was born Sarah Davies and I've not found any evidence that she married, though she had a daughter registered as Elizabeth Emily (Bessie) Minton in 1876, father Thomas Minton (shoemaker), mother Sarah Minton formerly Davies. But Thomas was already married. Bessie (Bessy) is with her grandparents in 1881 at 26 Mill St.
James Henry (1887) was baptised as the son of Sarah Davies 26 Mill St. Can't find a baptism for William.
There is a baptism for a Sarah Jane Davies on 14 Oct 1879 (born 11 Oct 1878), daughter of Sarah Davies, single woman, of the Union House. Interestingly, there's also one for Sarah Jane Davies on 28 Sep 1885, born 4 Sept 1878, daughter of Thomas, shoemaker, and Sarah, of 43 Mill St.
Hence I was hoping that the drowning story, tragic though it sounds, would have helped tie the family down.
Thanks for the interest.
